SULFUR-SPRAY APPARATUS.

Specification of Letters Patent.

Patented (15,111.29, 1918,

Application filed September 19, 1916. Serial No. 121,059.

To all whom it may concern:

Be it known that I, GIUSEPPE BIANCI-IIN, a subject of the King of Italy, residing at Treviso, Kingdom of Italy, have invented certain new and useful Improvements in Sulfur-Spray Apparatus, of which the following is a specification.

The present invention relates to improvements in apparatus for spraying sulfur on vines, and more particularly in that type of apparatus wherein the pulverized sulfur contained in the upper or charging compartment of the apparatus falls therefrom into a lower compartment from which it is blown out by a current of air forced therethrough,

T he=objects of the improvements are to facilitate the action of the pulverizing de vice, to enable its adjustment according to the character of sulfur being used, and to simplify the charging operation.

An embodiment of the invention is illustrated in the accompanying drawing, in which Figure 1 is a vertical section of the improved apparatus.

Fig. 2 is a vertical cross-section on line 22 of Fig. 1.

Referring more particularly to said drawing, A indicates an upper compartment or chamber within the interior of the casing of the apparatus; and B indicates a lower compartment or trough, also within said casing, disposed centrally beneath the upper compartment, the two compartments being separatedby a concave partition plate J. This plate J is perforated, as shown; and the sulfur, after having been reduced to powder in the upper compartment by means of the subsequentlydescribed pulverizer, falls through the perforations into the trough B, the wall of which is formed by the depressed central portion of a second plate N, below which the bellows C is arranged. The upper compartment A is sub-' stantially hopper shaped, and its bottom wall is formed in part by the concave plate J and in part by the inclined outer portions of the plate N. the top wall of the compartment being provided with a charging opening I, which is closed by a cover I, the latter having affixed to it a spout I".

The bellows C, as here represented, is of the double-acting type. and comprises a flat, plate-like element which is disposed horizontally and is lexibly connected with the walls of the casing. It is designed to be reciprocated upward and downward, and is preferably actuated by a crank shaft H, the latter connected to it at one end and at the other end with a hand-oscillated lever G. The bellows compartment and the trough or receiving compartment B are in communication by way of a series of openings or ports, most of which are equipped with controlling valves, and these openings are so arranged that the bellows, at each stroke thereof, draws in a quantity of air on one side of it and eXpels the air on the other side out through a discharge opening or nipple at one end of the trough, to which nipple the spraying device proper F is attached. Thus, when the bellows ascends, it draws in air beneath it through the valve opening D and the port D, and forces the air above it out through the valve opening E into the trough, where it takes up the powdered sulfur, and thence through the nipple F into the sprayer. When the bellows descends, it draws in air above it through the valve opening E, and forces the air below it out through the port D" and the valve opening D into and through the trough and thence through the nipple and the sprayer.

The pulverizing device is located directly above the perforated plate J, and consists of a swinging scraper L, formed by a horizontally-disposecL-metal plate having its longi-m tudinal edges turned down so as to rub the sulfur against the first-named plate. The scraper plate L is adjustably connected by a pair of threaded bolts L with a horizontal rock shaft K", so that it can be moved toward the latter ,against the action of a pair of coil springs L, which encircle said bolts and press the plate outward toward plate J the arrangement being such, therefore, that the distance between the edges of plate L and the perforated plate J can be varied to suit different working conditions and different kinds of sulfur. The scraper plate is cut away at L to provide openings for sulfur to fall therethrough upon the perforated plate; and its operation is effected by the same lever G that is utilized to actuate the bellows, said lever having joined to it a vertical rod K, which is connected to rock shaft K" about its longitudinal axis by means of a crank arm K. Consequently, the manipulation of lever G operates not only the bellows, but also the pulverizing device.

The latter device is designed for removal bodily from the apparatus; and for that purpose, the perforated plate J is made separable from the plate N, and is held in place at its rear end by means of a guide N, which supports said end and is fixed in some suitable manner to the casing. T he plate J carries at its inner end a standard J, and at its outer end a vertical cover plate J which closes an opening in the adjacent Wall of the casing and supports the front end of said plate, the parts J and J" having bearings wherein the ends of the rock shaft K are journaled. By reason of this construction, the entire device may be readily Withdrawn through the opening in the casing Wall and then replaced; and since the standard J" and cover plate J are rigidly fastened to the plate J and, in turn, carry the shaft K", the scraper L Which is fastened. to said shaft Will be removed With the latter, as Will be understood.

I claim as my invention 1. In an apparatus of the character specified, the combination, with a casing having an opening in one Wall thereof; of a perforated bottom plate adapted to be inserted through and Withdrawn from said opening; a standard fixed to the rear end of said plate; a cover fixed to the front end of said plate to close said opening; and a pulverizing device supported at opposite ends by said cover and standard and adapted to dis charge the pulverized material through the perforations in said plate during its operation.

2. In an apparatus of the character specified, the combination, with a casing having an opening in one Wall thereof; of a perforated bottom plate adapted to be inserted through and Withdrawn from said opening; a standard fixed to the rear end of said plate; acover fixed to the front end of said plate to close said opening; a horizontal. shaft supported at opposite ends by said cover and standard; a depending scraper carried by said shaft and embodying a plate having opposite edges thereof turned downward; and means for rocking said shaft so as to swing the scraper plate backward and forward across the bottom plate, tiereby to pulverize the material under treatment and discharge it through the perforations in said bottom plate; said scraper plate being normally forced toward said bottom plate, but adjustable away from the same, to regulate the distance between its said edges and said bottom. plate.

In testimony whereof I aflix my signature.

GIUSEPPE BEANCHEN.
